1Story

From the road, a house; from the drive, three overhead doors on one gable end. The Caprock is a single-story 3-bedroom, 2-bath barndominium, about 2,300 square feet on a 40×90 footprint: a vaulted living and dining room with an open kitchen, a walk-in pantry, an office, a mud room, and porches front and back. The shop and 2-car garage share one open bay, no wall between them. Roll the doors down and the rest is home.

The Floor Plan

Presentation floor plan. Room areas are finished square feet. Kitchen and bathroom layouts are illustrative; the final design is yours. Written dimensions govern over scaled dimensions.

Key Features

  • A 30′ × 14′ shop open to a 30′ × 26′ garage, one work bay with transom windows (short windows set high in the wall) on the front and back walls
  • Three 10 foot wide overhead doors on the west gable end (the end wall, under the peak of the roof), two into the garage and one, 10 feet tall, into the shop
  • A mud room between the garage and the house under a tubular skylight, with a storage room beside it and the laundry off the same hallway
  • A vaulted 29′ × 24′ living and dining room with twin windows on the front wall, open to a 22′ × 16′ kitchen with a sliding door onto the rear porch
  • A 7′ × 9′ walk-in pantry behind a barn door (a door that slides on a track outside the wall)
  • A master suite on the east end wall, vaulted, with its own bath and a 6′ × 16′ walk-in closet
  • A 14′ × 9′ office off the foyer, windows on two walls, a closet of its own
  • Two more bedrooms off the hall, one at each end: Bedroom 2 at 12′ × 11′ with a twin window, Bedroom 3 at 17′ × 11′ with two windows on the front wall, each with a closet
  • Five tubular skylights pulling daylight into the hallway, hall bath, storage room, mud room and foyer
  • Porches front and back, 46 feet each, 736 square feet in all
  • Three cupolas on a 5:12 gable roof, over a 12 foot eave at the house

Is This Plan Right for You?

A great fit if you want

  • a 30′ × 14′ shop open to a 30′ × 26′ garage, one work bay with three 10 foot overhead doors on the gable end
  • a mud room between the garage and the house, so the day comes off at the door and not in the kitchen
  • a vaulted 29′ × 24′ living and dining room with the kitchen open to it and a foyer at the front door
  • a master suite on the end wall with its own bath and a 6′ × 16′ walk-in closet, and a 14′ × 9′ office off the foyer

Tour The Caprock

The Heart of the Home

Cross the foyer from the front door into the 29′ × 24′ living and dining room, vaulted. The 22′ × 16′ kitchen opens across its back with no door between, vaulted too, a sliding door onto the rear porch and the walk-in pantry behind a barn door. Whoever is cooking sees who comes in through the foyer.

The Shop

Roll in under three overhead doors on the west gable end: two into the 30′ × 26′ garage and a third, 10 feet tall, into the 30′ × 14′ shop behind it. Garage and shop are one open bay across a dashed line, not a wall. Whoever has a project going leaves it out and still parks both cars.

The Master Suite

At the east end the 14′ × 15′ master bedroom opens off the living room, vaulted, a twin window on the end wall. Its own bath opens off it, and beside the bath, with its own door from the bedroom, a 6′ × 16′ walk-in closet. Whoever sleeps here shares no wall with another bedroom.

Work & Service

Step in from the garage into the 12′ × 5′ mud room under a tubular skylight and into the hallway. The storage room is beside the mud room, the laundry down the hall behind a barn door. The 14′ × 9′ office opens off the foyer, windows on two walls. The office takes the paperwork, the mud room the boots.

Outdoor Living

Step out the front door onto the 8′ × 46′ front porch, deep enough for a table, running along the front from the garage to the foyer. The matching porch runs along the back from the shop to the kitchen, under the kitchen's sliding door: 736 square feet under cover. Whoever breaks for lunch eats it on the front porch.

Not included, handled by local professionals

  • Foundation design: by your local structural engineer for your site, using the anchor bolt plan and loads from your building supplier
  • Engineering drawings for the structure (provided by your chosen supplier)
  • Plumbing, electrical and HVAC layouts, by your local trades to local code

Can I Build This?

Yes: every page is designed for standard pre-engineered metal building (PEMB) construction. Stamped structural drawings come from your building supplier's engineer, and permit review is with your local building department.

Why a pre-engineered metal building?

A PEMB encloses more home for the money than a wood-framed building and goes up in weeks. Its steel frames carry the roof, so no inside wall has to hold it up: the living room, kitchen and master bedroom can be vaulted, and the shop end steps up to a 14 foot eave. The frame layout on these pages follows standard metal building practice, so a supplier can quote it as drawn.

Who does what

We design the home: the rooms, where the doors and windows go, the elevations and the roof. Your building supplier engineers the steel frame for your site and confirms the vaulted ceilings against it. That is the usual split on a metal building project, and our pages are drawn to it.

Every plan is designed and informed by the IRC (USA) and NBC Part 9 (Canada): room sizes, bedroom egress windows and door and hallway clearances are checked on every plan before it goes on sale.

Steel or wood?

Same home, same rooms, same plan set, same price. What changes: what holds the roof up, who builds it, how you get a price.

Steel framingWood framing
Shell goes up✓Faster: the frame and panels arrive cut and drilled, bolted up in a week or two.Slower: framed on site, stick by stick, over several weeks.
Getting startedMade to order; allow factory lead time.✓Lumber is on the shelf; start when the slab cures.
Waste on site✓Little; cut to size at the factory.More; offcuts and scrap.
Crews and materialsNeeds an erector who knows metal buildings.✓Any framing crew and lumber yard.
Inspectors, appraisers, lendersMost know steel homes; a few ask questions.✓Everyone knows a stick-framed house.
Open interiors✓Nothing inside holds the roof up: the frame clears the whole width, so walls can move and rooms open up.On our 40 ft span plans one interior wall carries the roof trusses and stays put; the rest are partitions.
The look inside✓Steel columns and beams can stay exposed, or be boxed in.✓Conventional walls and ceilings.
Insulation✓Blanket or spray foam between the steel.✓Standard batts in the 2x6 walls.
Sustainability✓Recycled content; recyclable at the end of its life.✓Renewable; keeps storing carbon for the life of the house.
Termites, rodents, decay✓The frame does not rot or feed termites.Open to termites, rodents and decay unless kept dry and treated.
Fire and fire zones✓Non-combustible frame, walls and roof: what wildfire codes ask of the outside of a house, and a class insurers rate.Metal roof and panels help; the framing behind them is combustible.
Insurance✓Often priced lower; ask your insurer.Standard homeowner rates.
Who engineers itYour building supplier's engineer, stamped, in the package.Your roof truss company's engineer; walls to code as drawn.
Cost to build this plan$440,000 to $490,000$530,000 to $580,000

How you get a price

Steel framing

With the design set, get shell quotes from metal building suppliers (they engineer the frame for the size and shape of this home and your local wind and snow loads); upgrade to the construction set (coming soon) for firm bids from local trades on the slab and interior.

Wood framing

With the design set, get budget quotes this week from a local framing contractor and a roof truss company you already know; upgrade to the construction set (coming soon) for firm project bids.

Pick the framing your local builders can quote; the rooms are the same either way.

What Will It Cost to Build?

$440,000 to $490,000

A home like The Caprock is estimated to complete for $440,000 to $490,000 with you as your own general contractor, hiring the trades yourself. That covers the steel building and putting it up, the foundation, the inside finish, and an allowance for site work, utilities, driveway and septic.

It leaves out land, financing, sales tax, payroll taxes and insurance on labor, appliances beyond a standard allowance, landscaping and window coverings. Hiring a general contractor adds about 15 percent.

This is a rough estimate, not a quote. Costs vary by region by 15 to 25 percent, and your building supplier and local contractors will price it for your area. Our barndominium buying guide walks through what moves the number.

Frequently Asked Questions

How big is the shop, really?

30′ × 14′, open to the 30′ × 26′ garage: one bay at the west end, 40 feet across the door wall and 30 feet deep. Three 10 foot wide overhead doors sit on that gable end, two 8 feet tall into the garage and one 10 feet tall into the shop. The house connects through the mud room.

Is the house half a real house?

Three bedrooms, two baths and an office. The living and dining room is 29′ × 24′ and vaulted; the kitchen is 22′ × 16′ with a sliding door onto the rear porch and a walk-in pantry. The master suite has its own bath and a 6′ × 16′ walk-in closet. Porches run 46 feet front and back.

Which rooms sit on the shop wall?

Bedroom 2 shares its west wall with the shop and Bedroom 3 shares its west wall with the garage; the hall bath, the mechanical room and the mud room sit between them on that same wall. The living room, kitchen, office and master suite are on the house side of the hallway and touch neither.

Can I build The Caprock with any metal building supplier?

Yes. Every page is designed for standard pre-engineered metal building (PEMB) construction, so any steel building supplier can quote this home as drawn. Their engineer then provides the stamped engineering drawings for the steel building, along with an anchor bolt plan and the loads for your site, and your local structural engineer designs the foundation from them.

Is the plan stamped, engineered, or permit-ready?

No. No plan set is a permit. This design set is for quotes, budgeting, and financing; permit review comes later, on a construction plan set (ours is launching soon) with the engineering your building department requires. The Caprock is designed and informed by the IRC (USA) and NBC Part 9 (Canada). Local permit review is between you, your builder and your building department.

Is a steel barndominium a good choice in a wildfire zone?

Yes, with the rest done right. The steel frame and the metal wall and roof panels do not burn, the kind of construction wildfire rules favor. A metal roof also carries the top fire rating, Class A. Ember-resistant vents, boxed eaves, tempered windows and cleared ground around the house decide the rest. No home is fireproof.
